SPECIFICATION forming part of Letters Patent No. 567,661, dated September 15, 1896. Application filed May 16, 1896. Serial No. 591,795. (No model.)

T at whom it may concern:

Be it known that we, GEORGE D. SANFORD, a resident of the city of Albany, in the county of Albany, and JOHN S. KILBY, a resident of the city and county of New York, State of New York, citizens of the United States, have invented certain new and useful Improvements in WVindows, of which the following is a specification, reference being had to the ac- 1o companying drawings, forming a part hereof. The object of our invention is to provide improved means for supporting verticallymovable window-sashes, so that they may be swung upon horizontal pivots, either for the I 5 purposes of ventilation or to permit them to be turned completely over to allow the outside of the window to be cleaned or repaired without requiring the operator to go upon the outside of the Window.

Various devices have been constructed or proposed to accomplish the same purpose; but so far as they are known to us they are unnecessarily complicated, or diflicultto operate, or liable to let in cold air at the side 2 5 when it should be excluded, or expensive.

It is the object of our invention to provide a construction which shall be simple and inexpensive, readily applied to any window,

and capable of excluding air at the sides as o efficiently as an ordinary window.

We will explain the features of construction wherein our invention consists hereinafter, with reference to the accompanying drawings, in which we have illustrated the 5 same as embodied in a convenient and practical form.

In the drawings, Figure l is a perspective view of a window and window-casing with both upper and lower sashes in their normal 0 position. Fig. 2 is a similar view of the same, but with both sashes swung into a horizontal position for ventilation. Fig. 3 is likewise a similar view, but with the lower sash shoved up out of the way and the upper sash brought down and swung completely over to allow the outer surface of the glass or sash to be cleaned or repaired from the inside of the room. Fig. 4 is a horizontal section on the plane indicated by the line 4 4 of Fig. 1. Fig. 5 is a perspective view of one corner of a sash to show details of construction. Fig. 6 is a perspective view of a portion of one of the auxiliary slides hereinafter referred to. Fig. 7 is a perspective View illustrating the application of our improvement to a barred window, one of the sashes being pushed to the bottom and swung down inwardly and the other being shown as removed and set one side, the latter being shown in rear view. Fig. 8 is a sectional detail View.

The casing A of the window is constructed substantially in the ordinary manner, and is provided at each side with the back stop a,

the parting-strip a, and the front stop a these parts forming guideways between them. The top of the casing, instead of being closed in, as usual, may be cut out, as at a to allow the lower sash to be shoved up farther than is ordinarily possible, for a purpose to be re ferred to hereinafter, although this is not absolutely necessary. The window is also provided, as usual, with the ordinary sash-cords a and :sash weights or springs, (not shown,) the sash-cords being connected to auxiliary slides B B, which move in the guideways formed by the stop-beads and parting-strips andhave a thickness at least as great as the depth of the guideways,

The upper sash O and the lower sash O are pivoted on horizontal pivots (indicated at c c in Figs. 2, 3, and 7 and shown in detail in Fig. 8) between the auxiliary slides B 13, fitting between them as snugly as maybe without causing the parts to bind in their movements. It is with the means for preventing the sashes from swinging on their pivots except when required that our invention is more particularly concerned. lVe have provided two devices for this purpose which cooperate to effect the most desirable result and are preferably employed together, although, as will be apparent, either device is capable of use by itself.

As has been observed already, the auxiliary slides B B have a thickness as great as .or greater than the depth of their guideways, so that the sashes may swing freely between the opposing stop-beads.

WVe hinge to each back stop Ct an auxiliary back stop a and to each front stop an aux iliary front stop a", the said auxiliary stopbeads being hinged to swing outward and inward, respectively, so that their surfaces may be flush with the surface of the fixed stops when it is desired to swing the sashes upon their pivots. When the sashes are to be held from swinging, the auxiliary stops are turned upon their hinges to stand against the sashes, respectively, and are held in position by suitable fastening devices, such as the bolt represented at a7.

It is evident that the auxiliary stops, as described, will retain the sashes from swinging, but that the latter might spring away somewhat from the fixed stops and therefore afford an opening through which the wind might find its way. Accordingly, we prefer to employ the second device, which we will presently describe, in connection with the first. This device comprises a half-round rod D, which may be seated wholly in a halfround groove d, formed in the edge of each sash. A substantially quarter-round groove d, of the same radius as the groove d and the rod D, is formed in the outer face of each auxiliary slide B in such position with relation to the groove d that the half-round rod.

D can be turned partly out of the groove d, so that its edge shall engage the groove cl.

As represented in the section of the upper sashin Figs. 4 and 5, the rod D is in position to engage the groove in the auxiliary slide B, while the rod of the left-hand portion of the lower sash in Fig. 4t and the rods for both sashes in Fig. 2 are represented as lying wholly in the half-round grooves d in the sashes, so that the sashes are free to swing upon their pivots. hen the rods D D are in the latter position, they offer no interference with the swinging of the sashes, but when they are in the former position they not only hold the sashes from swinging, but effectually close the opening between each sash and its auxiliary slides and prevent the passage of air. The formation of the quarter-round groove in the auxiliary slide enables the proper movements of the rod D to be determined exactly, so as to lock the sash securely or to leave it free to be swung, the fiat side of the recess or groove forming a stop in one direction and the adjacent face of the slide forming a stop in the other direction.

Any suitable means may be employed for turning the rods D D, and we have represented in Figs. 2, 4, and 5 each rod as having secured thereto at one end an arm d carrying a pin which travels in a slot 01 formed in a plated secured to thes'ash, but any other suitable means, such as a button or knob, might be employed instead. It is not necessary to provide pivots for the rods nor any means for holding the rods in place, inasmuch as they are always, for at least some portion of their length, held between the sash and the auxiliary slides. It is evident that this last-described device might be relied upon by itself, but for greater security and to obviate the possibility of accidental release of the sashes we prefer to employ the hinged auxiliary stops in connection therewith.

The utility of our improved construction is particularly apparent when applied to barred or grated windows for asylums, hospitals, and other public institutions. We have represented such an application of our invention in Fig. 7, in which it will be seen that each sash is pivoted to the auxiliary slides near the bottom of the sash, so that it may be turned to a horizontal position without striking the bars on the ,outsideof the window. Furthermore, it is possible to remove the sashes from the window without difficulty, thereby permitting them to be taken to the yard orelsewhere to be washed. To facilitate such removal, the pivot-pin 0 (see Fig. 8) is provided at its outer end with a head 0, and at its other extremity is shouldered, as at c ,and threaded, as at 0 to engage a nut 0 which is seated in the auxiliary slide B, on the inner side thereof. Suitable bearing-sleeves c and c are inserted in the sash and in the auxiliary slide to receive the pin ,0, which, with a few turns, may be readily engaged with or disengaged from the nut c to secure the sash in place or permit its removal.

The mode of use of our improvement will be readily understood from the foregoing description without further explanation.

Ne claim and desire to secure by Letters Patent 1. In a window, the combination with a casing having guideways, auxiliary slides mounted in said guideways and a sash pivoted horizontally between said slides, said sash and slides having in their proximate faces a half-round groove and a quarter-round groove respectively and a half round rod mounted in said half-round groove and arranged to be turned to enter said quarterround groove, the flat side of the quarterround groove and the adjacent face of the slide forming stops to determine the movement of said rod, substantially as shown and described.

2. In a window, the combination with areasing having a fixed parting-strip and a fixed stop-bead on each side to form a'guideway between them, auxiliary slides mounted in said guideways, a sash pivoted horizontally This specification signed and witnessed this 14th day of May, A. D. 1896.
